Hi, Samantha!
Thank you so much for the follow-up question! I am sorry to hear the Studio rooms at Disney's Polynesian Villas & Bungalows were already all booked for April, I think you would have loved it there.
If you're looking for a Monorail Resort with a bathroom design area similar to Disney's Beach Club Resort, Disney's Grand Floridian Resort & Spa, or the Studio Rooms at Bay Lake Tower at Disney's Contemporary Resort, are your two options (Disney's Contemporary Resort rooms do not have the separate sink area).
Disney's Grand Floridian Resort & Spa rooms are setup just like Disney's Beach Club Resort, but with more square footage. The Grand's rooms are 440 sq. ft. and Disney's Beach Club rooms are 381 sq. ft.
The Studio rooms at
Bay Lake Tower at Disney's Contemporary Resort offer a kitchenette area that would fit a pack 'n' play and still be separated from your sleeping area. These rooms are 339 sq. ft. You can select the highlighted links to view photos of both resorts.
I hope this helps, Samantha. And thank you so much for the compliment! The Disney Parks Moms Panel loves helping our guests plan magical vacations.
